A MUM has been left furious after her four-year-old son managed to sneak out of his nursery and walk home alone - without his teachers noticing.

Little Connor climbed out of the nursery window, got through two closed gates and walked for ten minutes to get home.

Mum Claire Frost couldn't believe her ears when she heard her little boy yelling through the family's letterbox "mummy please let me in".

And she has been left enraged after calling the Holy Trinity Nursery in Taunton, Somerset - with teachers not even realising her son had vanished.

The 32-year-old said: "I felt sick to my stomach when Connor showed up at the door.

"I couldn't believe what was happening."

The nursery has since apologised, saying a number of changes had been implemented - including adding combination locks and adjusting windows.

The mother-of-four said she has taken Connor out of the nursery since the incident as she does not trust it to look after him.

She added: "He's four-years-old. He could have been run over on the main road.

"My heart was racing when he came to the door.

"He burst into tears as he thought I would be angry at him but I wasn't. I was angry at the nursery."

The mum said: "I'm just really frightened that something more serious could have happened as a result of the incident."

Jeremy Handscomb, head teacher at Holy Trinity Primary School, where the nursery is based, said: "There was an incident with a four-year-old child from our nursery on Monday who left the school site.

"The alarm was raised very quickly and after a short period the child was returned to the nursery.

"This incident should not have happened and we apologise without reservation.

"This is a recently built and purpose-designed nursery provision and surrounding outdoor site which met all the health and safety requirements and building regulations and had up until Monday ensured the safety of all children.

"In the light of this incident and following an investigation we have immediately made some additional alterations to the safeguarding of the building and the wider area."
